Still, with Titanfall being released for the Xbox One, Xbox 360, and PC at the same time, it could do better than they expect, depending on how high the buzz is for the Xbox 360 and PC versions. Whispers suggest that EA does expect Titanfall to sell well for the Xbox One, with it likely that most who purchased the console will end up buying a copy.
Extra content is apparently already in the works for Titanfall, and the DLC will also be a big part in how well Titanfall actually does when everything is all totaled up.
